Djorgovski 1 is actually one of the most metal-poor clusters in the inner galaxy.[4] References1. ^1 2 3 {{cite web |title=Djorg 1 |url=http://spider.seds.org/spider/MWGC/djorg1.html |website=Spider.SEDS.org |accessdate=19 June 2015 |archiveurl=https://www.webcitation.org/6ZOqhKxDF?url=http://spider.seds.org/spider/MWGC/djorg1.html |archivedate=19 June 2015 |deadurl=yes |df= }} 2. ^{{cite web |last1=Valenti |first1=Elena |last2=Ferraro |first2=Francesco R |last3=Origlia |first3=Livia |title=Near-IR Properties of Globular Clusters in the Galactic Bulge |url=http://www.bo.astro.it/~GC/ir_archive/ |accessdate=19 June 2015 |archiveurl=https://www.webcitation.org/6ZOr7Jq5B?url=http://www.bo.astro.it/~GC/ir_archive/ |archivedate=19 June 2015 |deadurl=yes |df= }} 3. ^{{cite journal |last1=Djorgovski |first1=S |title=Discovery of three obscured globular clusters |journal=The Astrophysical Journal |volume=317 |pages=L13 |bibcode=1987ApJ...317L..13D |doi=10.1086/184903|year=1987 }} 4. ^{{cite web |title=Engulfed by stars near the Milky Way’s heart |url=https://www.spacetelescope.org/images/potw1126a/ |website=Hubble Space telescope |accessdate=19 June 2015 |archiveurl=https://www.webcitation.org/6ZOv08Z5w?url=https://www.spacetelescope.org/images/potw1126a/ |archivedate=19 June 2015 |deadurl=yes |df= }} 2 : Globular clusters|Scorpius (constellation) |
